CONTEXT-AWARE METHOD AND SYSTEM FOR SUPPORTING ENERGY EFFICIENCY AND APPLICATION EXTENSIBILITY IN USN

摘要

The present invention relates to a context-aware method and system capable of improving energy efficiency such that: a USN sensor node determines context on the basis of context information received from a sensor, and transmits a context determination result to a central server only when the context determination result is included in a danger determination condition; and the central server deals with the context on the basis to the transmitted context determination result so as to reduce data transmission overhead.
